TOBACCO PIPE.

Application filed March 28, 1921. Serial Hi0. 456,453.

To aZZ whom it may concern:

Be it known that l[, FLOYD E. LASURE, a citizen of the United States ofAmerica, and a resident of Waukesha,Waukesha County, Wisconsin, haveinvented certain new and useful Improvements in Tobacco Pipes, of whichthe followin is a specification.

My invention re ates to improvements in tobacco pipes, and the objectsof my improvements are, first, to construct the bowl of a i e ofconcentric layers of difierent materia s selected to render the samemore sightl lasting, and comfortable in use, and second to'supply meansfor regulating the draft thereof, this means being contrived also foroccasional employment as a cleaning element for the draft hollow of thepipestem.

These objects I have accomplished by the means which are hereinafterdescribed and claimed, and which are illustrated in the accompan ingdrawings, in which Fig. 1 is a medial ongitudinal section ofmy improvedpipe; Fig. 2 is a plan of the same; Flg. 3 IS a medial transversesection of the pipebowl, and Fig. 4: is a detail perspective view of theadjustable regulating and cleaning p S%milar numerals of referencedenote corresponding parts throughout the several views.

The pipe bowl 1 has the usual angular shank or stem 5 hollowedlongitudinally at 6 to receive a diminished end of a mouthpiece 7 whoselon itudinal bore 8 communicates with said ollow, said hollow alsocommunicating by means of an elongated slot 4 with the interior 16 ofthe bowl.

The cylindrical hollow 6 opens through the base of the bowl and is ofconsiderable diameter in order to receive and fit a removable rock-plu10 whose outer end is enlarged to provi e a rounded finger-piece 9. Saidplug is provided with short inclined grooves 11 and 12 positioned onopposite sides thereof with their inner ends in communication with saidhollow 6, and their outer ends closed within the pipe base. Grooves 11and 12 may be of difierent dimensions and said plug may be rocked toplace eit er of them into full communication or adjustably restrictedcommunication with said slot 4: to vary the draft of the pipe, or thegrooves may be placed out of communication with the slot 4.

The adjustment of the draft by rocking the plug 10 insures evencombustion, whatever may be the texture, quality, of humidity of thetobacco.

The numeral 13 denotes a pair of small rods projecting fixedly from theinner end of the plug 10 and carrying on their other ends a fixed disk14 having a central opening 15. This disk 14 is of the same diameter assaid plug, and therefore, fits the walls of and the stem 5, and renderthem more lasting and comfortable to use, I prefer to construct the bowlpart of concentric layers of substances of differing properties. Theouter shell or body 1 and 5 of said bowl and stem is preferably made inone piece, from aluminum or the like, which is not only enduring but isvery light, and has a pleasing appearance and is easily molded intoshape. The next inner layer 2 is formed from some substance which 1snon-conductive to heat, such as asbestos fiber or the like, while theinner lining 3 may be made from baked clay or other substance of arefractory nature. It will be seen that both the inner and outer layersassure longevity as against the actions of heat or shocks respectivelwhile the intermediate layer 2 prevents heat being conducted to theouter shell in an uncomfortable degree. Other materials may be used forthe pipe layers which will preserve the said desired qualities.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is:

1. A tobacco-pipe comprising an open bowl and a tubular stem incommunication therewith, the base of the bowl having an opening incommunication with the bore of said stem, a rock-plug in part of thelength of said bore having a longitudinal groove to effect occasionalvarying size communication between said bowl b way of said groove, saidopening and t e bore of said stem when rocked arms on said plug, and anorlficed scraping disk mounted on said arms in said bore to fit thelatter and scrape its walls when the plug-is moved longitudinally.

2. A tobacco-pipe comprising an open bowl and a tubular stem incommunication therewith, the base of'the bowl having an opening incommunication with the bowl and with the bore of said stem, a removableplug in said opening grooved longitudinally to control the communicationbetween said bowl and the bore of said stem adjustably,

said bo-wl being-composed of different materials arranged in concentriclayers.

3. A tobacco-pipe comprising a bowl and a tubular stem-in communicationtherewith, an orificed scraping disk mounted slidably in the bore ofsaid stem, and a mouth-piece mounted on said stem having a diminishedinner end passing "through and fitting the orifice in said disk todeposit moisture forwardly of the disk in the bore of the stem.
